refer to the instructions that came with unit.

Unless the number was displayed in alternation with 888, leave the house and call 911. You need to have someone to check your appliances for incomplete burning, leaks in their exhaust piping or a vehicle that is running inside or too close to an air intake. The 203 is the current carbon monoxide reading. The 888 indicates a self-test and other number is only shown for test purposes.

Please stay safe.

Three things about this:
1 It may be under recall depending on its age and if it is over 10 years old, replace it.
2. The unit has a radio active source and should not be tampered with.
3. The information that you are asking for is proprietary and not available.

Detecotrs have a limited lifespan of 5-7 years. So sounds like you need new one (It's not worth to buy just a sensor). Take a look on amazon: Amazon com Carbon monoxide detector (watch out on reviews). I hope this was helpful. cheers

If this is a new site that has to be OK'd by the building inspector then he is a small minor deity and you must do everything you can to not tick him off or he'll run you thru the wringer, so put it where he says.
If it's a friend who is a building inspector then put 'em where you want them.
Mine are mounted on the ceiling.
Their site says 12".

smoke detectors work by smelling the air across a radioactive anode which upsets the electronics and sets off the alarm
it can be set off not only by smoke but by heat and gasses in the air
the new and better product is a photo electric detector which alerts earlier and can be installed connected to each room and into the house power or they come with a 10 years lithium battery
It could be a faulty unit so take it back for a warranty exchange unit

Try another hard whack. If that does not undo the initial damage, nada will and you have a nice paper weight.

The blinking green light is an indication that batteries need to be changed.
